According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, first location information included in a DHCPDISCOVER request can be used to determine appropriate configurations for networked devices. In some such implementations, the first location information is read from an RFID tag near the networked device and is inserted in the DHCPDISCOVER request. The first location information may include any type of absolute or relative coordinate, positioning, cartographic or similar information and/or information from which such information may be derived. Second location information, which may be a logical name, is provided to the device. If the device is an RFID reader, the second location information may be included with reads from RFID tags that are transmitted from the RFID reader.

Description

Equipment in location, supply and the recognition network
Technical field
The present invention relates to supply with the equipment in (provision) network.
Background technology
The bar code that comprises Universial Product Code (" UPC ") has become almost immanent feature in the modern life.Most products in the commercial stream and packing, container and other elements all have bar code now, control to allow to follow the tracks of easily with the stock.
But bar code has some shortcomings.Bar code is " read-only ", because they are one group of machine readable parallel strip that can not be updated of printing.Bar code can not be launched information, reads but must be scanned device.Bar code must be scanned in relatively short distance, and must be towards suitable direction, so that bar code is read.
For the shortcoming that overcomes bar code and add more strong functions, developed " intelligent label ", this " intelligent label " generally realized by the RFID label.The RFID label has been used to follow the tracks of article, for example clothes article, milk cow and the highway toll in aviation luggage, the retail environment.As shown in Figure 1, RFID label 100 comprises microprocessor 105 and antenna 110.In this example, RFID label 100 provides energy by the magnetic field 145 that RFID reader 125 is generated.The antenna 110 of label picks up magnetic signal 145.RFID label 100 bases are coded in the information modulated signal 145 in the label, and modulated signal 155 is transmitted into RFID reader 125.
Most of RFID labels use one of electronic product code (" EPC " or " ePC ") form to come information is encoded.The EPC sign indicating number can form all lengths (common form is 64,96 and 128 bits), and has the field of various types of definition, the information that these fields have allowed to discern individual products for example and have been associated.Define in the various documents of these forms in PD.This document be EPC Tag Data Standards Version 1.1 Rev 1.24 (
Figure A20058001516600071
2004), by reference it is incorporated into here, be used for all purposes.
An exemplary RFID tag format is shown in Figure 1.Here, EPC 120 comprises head 130, EPC supvr field 140, object type field 150 and sequence-number field 160.EPC supvr field 140 comprises fabricator's information.Object type field 150 comprises stock keeping unit (SKU) number of product.Sequence-number field 160 is 40 bit fields that can identify the particular instance of individual products uniquely, that is, and just certain pattern or model, but specific to specific " sequence number " of one style and model.
In theory, RFID label and the RFID equipment (for example RFID reader and printer) that is associated can be formed for following the tracks of the part of product (or product group) and historical network thereof.But various difficulties have hindered the realization of this theory.A problem that needs RF slip-stick artist to spend plenty of time and energy is the low cost RFID label that exploitation has acceptable performance level.Inductive coupled RFID label has acceptable performance level.These labels comprise microprocessor, wire coil and glass or polymer encapsulated material.Unfortunately, the material that is used for inductive coupled RFID label makes them too expensive for being extensive use of: the cost Yue Wei $1 of a passive button label, and the cost of battery-powered read/write label may the Wei $100 or more.
Capacitively coupled RFID label uses conductive ink to replace the wire coil that uses in the perceptual RFID label.Ink is signed at paper by the RFID printer prints, thereby produces lower-cost disposable RFID label.But traditional capacitive Coupled RF ID label has very limited scope.In recent years, RF slip-stick artist arrives above about one centimetre in the range expansion that labours for capacitively coupled RFID label.
Part since great effort solved on the foregoing problems by flower, so the prior art systems and the method for the RFID equipment that is used to network are quite original.RFID equipment just is deployed as recently and has network interface.Supplying with for the equipment of prior art RFID equipment is not automatically, but needs a time-consuming procedure to dispose each equipment.Prior art RFID equipment and system are not suitable for the large scale deployment of the network of RFID equipment.
And traditional RFID equipment has a spot of available memory.Typical R FID equipment may have the flash memory of about 0.5Mb and the total memory of 1Mb altogether.The small memory of RFID equipment has limited the scope to the possible solution of the problem of mentioning here.In addition, RFID equipment generally uses special purpose operating system, the fabricator's of (one or more) microprocessor that for example uses in the RFID equipment operating system.
In addition, many RFID equipment in disadvantageous industrial environment (for example warehouse or work) by technology unskilled relatively " IT " staffing.For example, if the equipment of disposing a position for example breaks down, then it may be replaced with regard to the equipment that just be removed and be used in the operate as normal of disposing another position simply.Therefore, be desirable to provide and be used for uniquely and individually discerning RFID equipment and they method and system in the definite position of network.
In addition, RFID equipment be deployed as equipment when having about initial deployment by " static state " knowledge of deployed position.In practice, if another device damage or malfunction, then RFID equipment is moved.Usually, wish to allow moving of RFID equipment.But if RFID equipment is moved, then prior art systems does not know where RFID equipment has been moved to.
Also wish to supply with these RFID equipment automatically at the desired use of these RFID equipment.RFID equipment is carried out different functions, and can be by different modes that depends on its position and up-stream system interface.The function that they are performed, and the unique setting that is used to carry out these functions here will be called as " individual character (personality) " of equipment.Not only wish to discern RFID equipment and also determine its position, also wish supply, configuration and deployment software and firmware, carry out various functions and role to allow RFID equipment position-based.Here employed " supplying with (provision) " equipment can include but not limited to provide network configuration, the individual character configuration is provided, equipment is attached in the network data base, and makes equipment can have software (for example business process software).It would also be desirable to provide heavily supplying with easily and the individual character renewal to RFID equipment.

Each RFID evaluation method selecting optimal equipment ground in the network 200 has " individual character " that is fit to its desired use.For example, if authorized people or object access door 223, then equipment 252 can impel to send and makes relieved tone and/or make green light flicker.But, go out or unwarranted people's access door 223 or go out from door 223 as fruit product from door 223, then equipment 252 may impel and sounds alarm and/or warning sent to keeper on the network 200.
Fig. 3 shows the RFID reader that can be configured to carry out method of the present invention.RFID reader 300 comprises one or more RF radio devices 305, be used for the RF ripple is transmitted into the RFID label, and reception is from the modulated RF ripple of RFID label.RF radio device 305 provides the original RF data of being changed and be transported to the miscellaneous part of RFID reader 300 by the analog to digital converter (not shown).In certain embodiments, these data at least temporarily were stored in the storer 315 by CPU 310 before being sent to other parts of network 200 via network interface 325.Network interface 325 can be the interface of any convenient type, for example Ethernet interface.
Flash memory 320 is used to store and is used to guide/program (" bootstrap loader ") of initialization RFID reader 300.Bootstrap loader is stored in the independent partitioned area of flash memory 320 usually, and it has also allowed RFID reader 300 to recover when power down, or the like.In some embodiments of the invention, flash memory 320 comprises and is used to control the instruction of CPU 310 with " DHCPDISCOVER " request of forming hereinafter with reference Fig. 6 and describing, to initiate supply/configuration cycle.In some implementations, flash memory 320 is used to store individual information and other configuration informations that for example obtain from Dynamic Host Configuration Protocol server during such cycle.
But in preferred implementation, this information only is stored in the volatile memory 415 by after for example Dynamic Host Configuration Protocol server receives.Keep RFID equipment " mute (dumb) " that some advantages are arranged.For example, the network of mute RFID equipment allows many processing loads to be put together (for example being carried out by the server 270 of network 200), rather than is carried out by RFID equipment.Perhaps, handle load and can be disperseed, but only be dispersed to the equipment (for example PC 247 of network 200) of being trusted.
Configuration information is for example by from central downloaded to storer 315.Renewal can be started by central server or the trusted device of choosing.The image file of redaction (for example operating the basic reflection of the necessary operation of RFID equipment) is copied in the flash memory 320.Other embodiment of RFID equipment have realized method of the present invention, but do not have flash memory.
More novel RFID equipment also comprises stem grafting touch I/O lead, to be connected to signal lamp, industrial network or equivalent.These more novel RFID equipment are generally in memory space, flash memory, CPU ability with determine development to some extent aspect the method for number, type and content of the RFID label in its visual field.
Fig. 4 is the block diagram that the exemplary RFID printer 400 that can be configured to carry out certain methods of the present invention is shown.RFID printer 400 has the identical assembly of many and RFID reader 300, and can dispose by the general fashion identical with RFID reader 300.
The RFID printer also comprises printer interface 430, and this interface can be the printer interface of standard.Printer interface for example according to via the instruction of network interface 425 from network 200 receptions, is mark of each RFID label printing.
RF radio device 405 is to spread out of radio device, is used under the control of CPU 410 to the antenna transmission RF of RFID label signal, thereby the information on the microprocessor of label (for example EPC) is encoded.Preferably, RF radio device 405 is checked the correctness of encoded information subsequently.The RFID label is pressed from both sides by in the mark that produces at printer interface 430.
Fig. 5 shows the rfid system 500 that comprises control section 501 and RF radio part 502.The assembly of control section 501 and above describe with reference to figure 3 and Fig. 4 those are similar substantially.The interconnection device 530 of control section 501 is arranged to the interconnection device 535 of RF radio part 502 and communicates by letter.Communication can be via any medium easily and form, for example wireless, serial, point-to-point serial or the like.Though only show a RF radio part 502 among Fig. 5, a plurality of RF radio of each control section 501 may command part 502.Rfid system 500 can be deployed on single frame or the cabinet in (for example on the fork truck) or a plurality of cabinet.
The DHCP agreement is used in preferred implementations more of the present invention, and this is because it provides multiple feature easily.For example, the DHCP agreement allows pond or " scope " of definition of T CP/IP address.Dynamic Host Configuration Protocol server can be given main process equipment with the interim distribution in these TCP/IP addresses or " leasing ".The IP address that is not used between the leasehold is returned to the pond of unappropriated IP address.In addition, Dynamic Host Configuration Protocol server will provide TCP/IP suitably all required relevant configuration settings of work, for example default router, domain name service (" DNS ") server, subnet mask etc.
For the implementation of using the DHCP agreement, DHCP option can be used to pass provisioning information.The DHCP agreement defines in RFC 2131, and DHCP option is for example set forth in RFC 2132,3004 and 3046.Here incorporate RFC 2131,2132,3004 and 3046 by reference into, be used for all purposes.
In some preferred implementations, be placed in from RFID equipment with the corresponding EPC of RFID equipment and send in the DHCP request of Dynamic Host Configuration Protocol server.EPC identifies RFID equipment uniquely.Some implementations have adopted domain name service (" DNS ") and dynamic-dns (" DDNS "), to allow more easily to discern RFID equipment.
With reference to the general view of Fig. 6 description to such implementations more of the present invention.Those of skill in the art recognize that and illustrate here and description and step not necessarily will be carried out with indicated order.In addition, will appreciate that, aspects more of the present invention can utilize than indication here more (or still less) step is carried out.Send to Dynamic Host Configuration Protocol server the equipment of the starting of IP address is finished this point by the grouping that comprises " DHCPDISCOVER " request.This order comprises medium access control (" the MAC ") address of equipment.According to some preferred implementations, RFID equipment (for example CPU 310 of RFID reader 300) forms " DHCPDISCOVER " request grouping, and it comprises the information (step 601) in the various DHCP option fields.It is the code of RFID equipment that this equipment is indicated in the RFID equipment utilization, to DHCP " classification logotype symbol " option 60 codings.In other words, " RFID " will be " vender class " that is coded in the newtype in the option 60.
In this example, RFID equipment is coded in the EPC of himself in the field of reserving into option 43 (because of the fixed information of manufacturer, definition in RFC 2132), option 61 or option one 25 (because of the fixed identification of the manufacturer information of manufacturer, definition in RFC 3925).RFID equipment also is coded in Business Name (for example providing, have or using the title of the company of RFID equipment) in the DHCP option 43.
According to different implementations of the present invention, can use option 77 (user class option, definition in RFC 3004) or option one 24 (identification of the manufacturer classification option defines) in RFC3925 by variety of way.In some implementations, option 77 or option one 24 will be used to indicate the type of RFID equipment, and for example RFID equipment is RFID reader or RFID printer.In some implementations, option 77 or option one 24 also can comprise about the function of RFID equipment or the information of " individual character ".For example, it is to import the RFID reader into, spread out of RFID reader or printer on RFID reader, the assembly line or in the retail shop that option 77 or option one 24 can be indicated RFID equipment, or the like.
Refer again to Fig. 2, if request from RFID equipment 252, then this equipment will be this equipment of indication that the information of RFID reader is coded in option 77 or the option one 24.In some implementations, option 77 or option one 24 also indicate RFID equipment 252 to have the individual character that is suitable for being placed on the entrance door place.Some implementations comprise the more details about the current individual character of equipment 252.For example, option 77 or option one 24 can be indicated except reading the EPC sign indicating number and they being uploaded to the RFID network, equipment 252 also will make if authorized people or object access door 225, then green light flicker, and go out then blinking red lamp, the alarm and warning sent to keeper on the network of sounding from door 225 as fruit product.This information for example can be according to encoding with one of a series of suitable individual characteies of the RFID reader at entrance door place corresponding numeral.
Hope is determined for the RFID equipment in the network and positional information is provided.Have the switch of Ethernet or switch ports themselves and wireless bridge and be considered to static, and have the Name ﹠ Location of appointment.According to implementations more of the present invention, the network equipment that positional information for example is attached to by RFID equipment adds in the DHCPDISCOVER request of RFID equipment (step 610).
Some such implementations are used DHCP option 82 (RFC 3046) in new ways, with switch ports themselves and the switch of determining that RFID equipment is connected to.For example, switch can be inserted into following two information elements in any DHCP request from attached RFID equipment: option 82, sub-option one: agent circuit ID (Agent Circuit ID); And option 82, sub-option 2: act on behalf of remote ident (Agent Remote ID).Agent circuit ID is the title or the identifier of switch.Acting on behalf of remote ident is the title or the identifier of switch ports themselves.
For example, if request is from the RFID equipment 226 of Fig. 2, then the network equipment 230 adds positional information in the request in step 610.Here, positional information will be coded in the option 82, and will comprise the network equipment 230 that sign RFID reader 226 is attached to and the information of port 216.
RFID equipment can determine that RFID equipment can be with location information coding in DHCPDISCOVER request or other orders other embodiment of position (for example from gps coordinate determine) of himself therein.
The Dynamic Host Configuration Protocol server that a plurality of service consolidated networks can be arranged.How server responds for example can depend on that each server is whether busy, whether it distributed its all address, or the like.Along with appearance and the development of RFID experimental network (pilot network), they will with the existing network weave in that comprises the network that adopts the DHCP agreement.The Dynamic Host Configuration Protocol server of provisioning RFID devices (for example server 270 of Fig. 2) will be to for example being coded in " DHCPDISCOVER " order for " RFID " of the classification logotype of equipment is responded in the option 60.Those of skill in the art recognize that other options also can be used for this purpose.On the contrary, the Dynamic Host Configuration Protocol server of provisioning RFID devices will not respond to " DHCPDISCOVER " order that device class is designated " RFID ".In addition, if non-RFID Dynamic Host Configuration Protocol server has been made response, then RFID equipment can be determined incomplete dhcp response from its received DHCP option response, and abandon it, and will be preferably from the response of RFID Dynamic Host Configuration Protocol server.Therefore, method of the present invention has allowed the RFID network is integrated in the available frame of DHCP agreement.
In step 615, whether Dynamic Host Configuration Protocol server determines in about the database of information of known RFID equipment, their expectation function and configuration etc. the information relevant for the equipment of the request of sending.For example, Dynamic Host Configuration Protocol server can be checked the EPC in the request of being coded in, and determines whether to be useful in database the information of the equipment with corresponding EPC.
If have, then in step 620, server is compared the information in the DHCP request with the information about RFID equipment of storage.This information may be in for example by in the IT personnel data updated storehouse of being responsible for the RFID network (for example being stored in one of memory device 265).For example, mac address information and EPC information can be combined, with sign particular device and the position in network thereof.The application of higher level can be apprised of that for example the particular RFID network is available.
The data that receive by inspection are so server can be determined type, identity, position and the individual character (if any) of RFID equipment.Compare with the information in the database by the data that will receive, so server can determine for example whether this RFID equipment moves and where it is in now.In preferred implementation, Dynamic Host Configuration Protocol server can be determined the current individual character (for example by checking option 77 data) of RFID equipment, and current individual character can be compared with desired individual character.
In step 625, Dynamic Host Configuration Protocol server provides configuration information of indicating in the database etc. to RFID equipment.For example, Dynamic Host Configuration Protocol server can be indicated position, the image file of configuration file of time server, SYSLOG server, the equipment of RFID equipment, or the like.The expectation individual character (if perhaps current individual character is not indicated in request) if the current individual character of RFID equipment does not match, then according to some implementations, Dynamic Host Configuration Protocol server can be provided for enabling to expect the information (for example computer program, configuration are provided with or the like) of individual character to equipment.
For example, suppose that EPC sign indicating number indicating equipment is a RFID reader 252, and option 77 indication RFID equipment 252 has the individual character that is fit to be placed on the entrance door place.But the positional information in the request may be indicated the equipment of the request of sending to be moved and is positioned at the outlet portal place now.Perhaps, database may be placed on the door place that is used as entrance door in the past but will be used as outlet portal now by indicating equipment.This may be manufacturing facility or place, warehouse periodicity (for example per hour, every day, weekly or every month) variation, perhaps may cause by reshuffling of facility.
Therefore, the expectation individual character of RFID equipment 252 is the individual character that is suitable for outlet portal now.But, may have the ability of the equipment that for example depends on the request of making, the desired use of outlet portal etc. and can offer a series of different " outlet portal " individual character of equipment 252.For example, the equipment with less ability (for example less storer) may be endowed better simply relatively outlet portal function.For example, the product that this equipment for example can be endowed in particular type makes the green light flicker when door is gone out, and transmits notification message and/or impel the ability of the alarm of sounding to the IT personnel under the situation that other article are gone out from door.
But the equipment with big ability can be endowed relatively complicated outlet portal function.For example, if, then make the ability of green light flicker if the product that equipment can be endowed particular type is gone out the number of the product of going out from door in expeced time to be in the preset range etc.
This dirigibility of reassigning device personality has allowed RFID network position-based, period or any other suitable standard, makes the identical device type have a plurality of individual characteies.In addition, this dirigibility has allowed moving of equipment or reorientation (no matter whether this moving is ratified in advance), and the equipment that makes then can " be weighed personalized " by automatically and be suitable for reposition.In addition, it has allowed the dedicated functions based on every equipment, every place.
But, in some cases, in database, may not have information about this equipment.For example, equipment may be the new RFID equipment (step 630) that just activates in the RFID network for the first time.In this example, equipment is placed at not being in " wall garden (walled garden) is arranged " of those equipment of the equipment of being trusted.Step 630 can comprise via DHCPOFFER order and is the not routable ip address in the time of equipment appointment predetermined length.According to some implementations, when in the database relevant for request in information inconsistency about the information of equipment the time, Dynamic Host Configuration Protocol server execution in step 630.
Preferably, step 630 comprises to higher layer applications announcement apparatus more and has made request.By this way, the IT personnel that are responsible for RFID equipment Location will be apprised of: RFID equipment has left and has made request.
According to some implementations, step 630 comprises that DHCP T1 timer is set to short time interval, for example 60 seconds.In this example, RFID equipment will send DHCP to server in per 60 seconds constantly and ask, and server will send " ACK " to equipment, takes place up to one of following two incidents: (1) server is updated (the IT personnel that for example are responsible for RFID equipment Location upgrade); Perhaps the connection between (2) server and the RFID equipment disconnects (step 635).
If server is updated in the given time, show that then the IT personnel have determined that the RFID equipment of the request of making is the equipment of being trusted.Therefore, method proceeds to step 625.If not, then equipment still is classified as the equipment (step 630) of trusting of not being subjected to.Preferably, the state of equipment still can for example be changed to the state of (the therefore being supplied to) equipment of being trusted according to IT personnel input subsequently.
Supply with configuration cycle (for example aforesaid) afterwards initial, RFID equipment may need to be supplied with again, and perhaps their individual character will be changed.The desired function of RFID equipment when as mentioned above, wishing that RFID equipment depends on particular moment and have unique supply and individual character.Desired function can be determined according to the position and the ability of RFID equipment.Some equipment may be provided to identical individual character in the relatively long time (for example some months or several years).But, may wish in the relatively short time, for example before DHCP T1 timer expiration, change the individual character and/or the supply information of RFID equipment.The RFID terminal device of most of current deployment is not supported RFC 3203 (DHCP reshuffles expansion).
The present invention includes the multiple method that is used to realize these targets.With reference to Fig. 7 a kind of such method is described.Method 700 starts from determining whether to the information (step 701) of network equipment transmission about the current individual character of RFID equipment.Here, if through one section preset time, then RFID equipment will send this information to Dynamic Host Configuration Protocol server.In this example, the preset time section is one hour time, but it also can be any time period easily.
If to another DHCPREQUEST or DHCPINFORM request should be sent to time of Dynamic Host Configuration Protocol server, then RFID equipment forms this request (step 705).If not, then current individual character is kept (step 702).In this example, information will be sent out in DHCP request (RFC 2131) in conjunction with DHCP option 125, option 61 or the option 43 of the EPC that is set to RFID equipment (or equivalent) and the option 77 that is set to the current individual character of RFID equipment.Utilize DHCPREQUEST, DHCPINFORM and DHCP option, RFID equipment can transmit current sign, supply and individual information.
In this example, the secret that is buffered (for example, utilize dhcp message content (comprising client EPC) and by the secret of Hash (hash)) will be comprised together with DHCP request so that guarantee the safety of response.This secret for example can be provided during the supply stage early, for example is provided during the initial supply stage of RFID equipment.This secret can be used to DHCPINFORM and confirm in process and other processes.
In step 710, request is sent out.Preferably, relay agent utilizes updating location information request, (step 715) as mentioned above.
In step 720, the information during server will be asked is compared with canned data (for example being stored in the information in look-up table or the database), to determine whether and need upgrade or reshuffle fully RFID equipment.If not, then process turns back to step 701.If then server provides necessary renewal and/or reconfiguration information (step 725) to RFID equipment.
Renewal in the RFID device trigger foregoing example and/or reshuffle definite.But in other implementations, another equipment (for example Dynamic Host Configuration Protocol server) and/or people initiate this and determine.For example, Dynamic Host Configuration Protocol server can initiate to expect the periodic process that the RFID device personality is compared with last known RFID device personality.Perhaps, IT worker can send the information (for example sending to Dynamic Host Configuration Protocol server, RFID equipment or another equipment) of the individual character variation of indicative of desired.
According to implementations more of the present invention, the defined DHCPFORCERENEW of Dynamic Host Configuration Protocol server utilization such as RFC 3203 (incorporate into by reference here its in full) orders and causes and upgrade or reshuffle fully.The CPU registration DHCPFORCERENEW order of RFID equipment, and begin the new supply cycle, for example top described with reference to figure 6.
For the safety that guarantees to order, in this example, the secret of buffer memory by Hash the order in.For example, secret can be included in by the EPC sign indicating number with RFID equipment.
A kind of method that is used to create authenticate key is as follows:
MD-5(EPC，Challenge，Secret)
By adding the variable of Challenge (challenge) at random, the Replay Attack of Hash code can not be used.Owing to comprised and further to have proved conclusively authentication from particular device by EPC.
Preceding method has allowed by the period rather than has come unique definite and provisioning RFID devices by equipment " type ", " classification " or " position " simply.In addition, preceding method has allowed the ongoing checking/verification to the role of terminal device.In addition, these methods have allowed the operational administrative person allow the ERP (Enterprise Resource Planning) control terminal, to allow greater functionality.
Fig. 8 is the process flow diagram that exemplary commercial application of the present invention is shown.Those of skill in the art recognize that the example of describing below with reference to Fig. 8 is one of many application of the present invention.
In step 805, RFID equipment is supplied to according to one of previously described method.The situation of the equipment at step 640 place in the situation of RFID equipment and the method 600 (shown in Figure 6 and above describe) is suitable.In this example, RFID equipment is near the RFID reader of outlet portal that is placed on retail shop.Therefore, in abovementioned steps, equipment has been supplied to the individual character that is suitable for its role.
In step 810, the shopper goes out from door with some products of choosing.In step 815, the RFID reader reads the RFID label of each product, and extracts EPC sign indicating number and relevant product information (for example price of each product).
The RFID reader also reads the sign shopper and the shopper should be by the RFID label of (one or more) of debit preferred account in order to buy product.For example, the shopper may have the RFID label in the place easily that is embedded in card, key chain or any other this information of wherein encoding.Account can be various types of accounts of being safeguarded by one or more financial institutions.For example, account can be one or more in checking account, savings account, line of credit, credit card or the like.Biometric data (for example voice, fingerprint, retina scanning etc.) from the shopper also can be obtained, and compared with the biometric data of storage, so that checking shopper's identity.
In step 820, the RFID reader transmits product information on the RFID network, comprising the EPC sign indicating number.In this example, information at first is sent to the financial institution by shopper's RFID label indication.
In step 825, safeguard that the financial institution of shopper's selected account determines whether the product that enough funds (or sufficient credit is not arranged) are chosen for shopper's purchase.If have, then shopper's account is by debit, and (step 830) finished in transaction.
In this example, the shopper can select to indicate one or more alternative accounts.Therefore,, determine then whether (for example being determined by the server on the RFID network) shopper has indicated any alternative account to be used to buy (step 835) if first account does not have enough funds or credit.If then next account is evaluated in step 825.If determine that in step 835 shopper does not indicate extra account, then in this example, the human intervention of certain form takes place.For example, the cashier of retail shop can help the shopper to buy in mode easily.
Purchased as in the fruit product some or all, then the information (comprising the EPC sign indicating number) about the product bought is transmitted on the RFID network.For example, this information preferably is forwarded to the one or more equipment (step 840) on the RFID network, and described one or more equipment are configured to upgrade one or more databases of being safeguarded by the fabricator/producer of the retail shop or the product of buying, allocation person, wholesale person etc.In some implementations, the information about the shopper also transmits (for example, if the shopper has authorized this information that discloses) on the RFID network.This product information (and shopper information (optional)) can be used to various purposes, for example is used for the formation (for example restock, market, sell, allot and make/production schedule) of various types of commercial plans.
Some embodiments of the present invention provide other methods of supply arrangement, and described equipment includes but not limited to RFID equipment.Wait some such methods of description with reference to Fig. 9.
In Fig. 9 A, RFID reader 905 is communicated by letter with switch 910.This communication can be carried out via wire link, shown in the optional link 915 between RFID reader 905 and the port 917.Perhaps, this communication can be carried out via Radio Link, for example carries out via the Radio Link 920 between the antenna 927 of the antenna 925 of RFID reader 905 and access point 930.RFID equipment 907 is connected to port 919 via circuit 918.
Switch 910 and switch 912,914 can be communicated by letter with Dynamic Host Configuration Protocol server 935 via network 940 with 916.Network 940 can be the network of any convenient type, but at least a portion of network 940 comprises the part of the Internet in this figure.
In implementations more of the present invention, Dynamic Host Configuration Protocol server 935 is carried out being carried out by equipment 945 of task in other implementations.Equipment 945 can be one of various types of computing equipments, comprises main process equipment, server or the like.In some implementations, equipment 945 is Lightweight Directory Access Protocol (Lightweight Directory Access Protocol, " LDAP ") servers.LDAP is the one group of agreement that is used for the visit information catalogue, and it is based on the standard that comprises in the standard X.500, but much simple.With X.500 different, LDAP supports TCP/IP.In some implementations, Dynamic Host Configuration Protocol server 935 and equipment 945 are in the same cabinet 950.In other implementations, Dynamic Host Configuration Protocol server 935 carries out direct communication (shown in link 955) with equipment 945 or communicates by letter via network 940.
Therefore, RFID reader 905 can be read RFID label (including but not limited to location tags 960), and transfers them to the equipment of communicating by letter with network 940.Preferably, location tags 960 is placed in the relatively-stationary position, for example is installed on other structural elements of wall, doorframe or buildings.In further embodiments, location tags 960 is of portable form.
Location tags 960 comprises here the thing that is referred to as " position data ", " positional information " and so on sometimes.Positional information can comprise absolute or relative coordinate, location, mapping or the similar information of any convenient type and/or can therefrom derive the information of this information.For example, in some implementations, location tags 960 comprises lat/lon, X, Y coordinate information and/or altitude information.In other implementations, location tags 960 comprises " civilian address " information, and it can comprise street address, buildings, floor, room/zone and/or other such information.
Perhaps, positional information can take therefrom to derive the form of the code of absolute location information (for example coordinate, lat/lon, civilian address etc.), for example numeral or alphanumeric codes.For example, can be comprised code and corresponding absolute location information by the data structure of Dynamic Host Configuration Protocol server and/or equipment 945 visits.Therefore, Dynamic Host Configuration Protocol server and/or equipment 945 addressable data structures, and determine and be coded in the corresponding absolute location information of code in the location tags 960.Data structure can be look-up table, database etc.Data structure can be stored in the local storage or the memory device 947 of one or more networkings in.
Intermediate equipment server 952 and 954 provides data aggregation and filtering services, and for example taking-up is redundant, the search particular RFID tag reads the result, or the like.Therefore, only some is made to the higher level application available routinely in the data that the intermediate equipment server is received.The intermediate equipment server is called as " ALE " (application level incident) equipment etc. here sometimes.
The IT personnel of surveillance, investigation fault etc. can use such equipment such as management station 957, and it is desktop computer in this example.Management station can be configured to receive, show and analyze the original and/or filtered result of reading, and carries out such as the such follow-up work of equipment in the inquiry network.
Location tags 960 can any mode easily be encoded, and comprises by exclusive method and/or to the method that small part is followed existing standard encoding.The general location tags of wishing to dispose according to the existing standard coding so that simplify the programming of relevant device, is avoided the nonuniqueness problem, and general the reduction realized cost of the present invention.Location tags 960 for example can form the bar code of RFID label or any kind.An example of the form of at least a portion of location tags 960 is shown in Fig. 9 B.Here, location tags 960 is taked the general format of global location number (" GLN ").The for example definition in " Global Location Number (GLN) ImplementationGuide " (Uniform Code Council, 2002) of some exemplary GLN forms is incorporated it into here by reference, is used for all purposes.Therefore, location tags 960 comprises 13 GLN.Field 965 is company's prefix fields, and its indication is assigned to the prefix of entity by the unified code council (Uniform Code Council) or EAN member organization.Field 972 is check digit fields, and it comprises the one-bit digital that is used to guarantee data integrity.
Reference by location field 970 is one nine bit field in this example, and its length changes according to the length of company's prefix field 965 of appointment.Reference by location field 970 can designatedly identify the position of choosing uniquely.Therefore, reference by location field 970 can customize according to the hope and/or the requirement of tissue.In the example shown in Fig. 9 C, reference by location field 970 is defined according to 975,2 floor field 980,1 bit function fields 985 of 3 buildings fields and 3 area fields 990 by certain entity.In this example, the position is the specific door in the receiving area in warehouse.
Figure 10 is the process flow diagram of summarizing the method according to this invention 1000.In step 1001, device initialize.According to method 1000, equipment obtained position data (step 1005) before it is configured to IP address and other network configuration informations.
In implementations more of the present invention, in step 1005, obtain position data by near the location tags that reads being positioned over.Therefore, location tags before had been placed in the position that the equipment expection is used.The identifier and the optimum seeking site of location tags are recorded in the center management system.In some such implementations, when equipment (for example wireless RF ID reader) when being switched at first, device prompts user crosses location tags with reader " brush ".If for example location tags is that RFID label and reader can then not need to brush operation in sufficient distance place reading tag.
In other implementations, in step 1005, obtain position data according to additive method, for example obtain from associate device with GPS (" GPS ") ability.In some such implementations, equipment itself comprises the GPS function.
In step 1008, position data is included in the Option Field of DHCPDISCOVER request, for example is included in option 43 (RFC 2132) or the option one 25 (RFC 3925).Here by reference these RFC are incorporated into, be used for all purposes.The DHCPDISCOVER request is sent to Dynamic Host Configuration Protocol server (step 1010) subsequently.
In step 1015, determine whether to determine from the position data the DHCPDISCOVER request position of equipment.Determining step comprises from the Option Field extracting position data of DHCPDISCOVER request.As mentioned above, in some implementations, position data can be to can be used for cross reference is supplied with the significant objective position data of purpose possibility to equipment code.In other implementations (described with reference to figure 9B and 9C for example), this objective position data is coded among the request itself.
Determine and/or the process of assess location data can be by Dynamic Host Configuration Protocol server (for example by Fig. 9 A Dynamic Host Configuration Protocol server 935) execution itself, or carry out by another equipment (for example equipment 945 of Fig. 9 A) to small part.With step 1015,1018 and 1020 relevant information can be by one of these equipment, by local memory device or by memory device 947 storages (seeing Fig. 9 A) of networking.If can determine objective position data in step 1015, then process proceeds to step 1018.If not, then process finishes.
In this example, by the objective position data of encoding of the mode shown in Fig. 9 C, and determine that in step 1015 equipment is positioned near the receiving gate of certain floor in indicated warehouse.In step 1018, determine whether storage with step 1015 in the corresponding configuration data of objective position data determined.In step 1015 or the step 1018 any one (being step 1018 in this example) for example also comprises determines device type according to the method for this paper other places argumentation.Here, in step 1018, determine the RFID reader that equipment is particular type.In addition, the configuration data of determining the position that is suitable for such RFID equipment and is suitable in the step 1015 determining in step 1018 before was stored.In this example, determine the position data of equipment in step 1018, for example logical name also is available.
Therefore, in step 1020, obtain the operation system image of suitable IP address, other network configuration informations, position data and RFID reader.This data are collectively referred to as " configuration data " etc. here sometimes.In this example, suitable device personality also is stored.This individual character is definite in step 1018, and exchanges by dhcp message in step 1020, utilizes one or more DHCP option to be provided.For example, positional information based on coordinate can be returned, by reference this RFC be incorporated into here in " DHCPOption for Coordinate-based Location Configuration Information (being used for the DHCP option based on the position configuration information of coordinate) " (RFC 3825).Civilian address location information can (draft-ietf-geopriv-dhcp-civil-04) be returned at " DHCP Option for Civic AddressesConfiguration Information (DHCP option that is used for civilian address configuration information) ", also by reference it is incorporated into here.Other location tags can " Vendor-Identifying Vendor Option manufacturer's option of manufacturer (sign) " (RFC 3925) form return, by reference this RFC is incorporated into here.Logical name can return via DHCP option 12.
DHCP and DNS can finish location-based supply.Dynamic Host Configuration Protocol server can return the address of " at random " and give the RFID reader from address pool, also specific Hostname can be returned to the RFID reader.Intermediate equipment generally has and corresponding pre-configured particular ip address of particular RFID reader or particular host title.Clearly visible for a person skilled in the art is, if Dynamic Host Configuration Protocol server is distributed the IP address of " at random " from the pond, particular ip address is hard-coded in the intermediate equipment inoperative so.
Therefore, in implementations more of the present invention, specific Hostname is hard coded within the intermediate equipment server.When Dynamic Host Configuration Protocol server is returned with particular RFID reader corresponding " at random " IP address, its renewable dynamic-dns server.Dns server arrives specific Hostname with " at random " IP address binding.In this case, because Dynamic Host Configuration Protocol server is assigned to equipment based on the position (for example from DHCP option 82 information) of equipment with Hostname, can guarantee that like this IP address is bound to correct Hostname.
Equipment is disposed accordingly, for example (step 1030) as described elsewhere herein.In some preferred implementations, the intermediate equipment server will be indicated reader with any form of intermediate equipment server appointment positional information to be included in each label and be read in the result, and described form for example is the logical name (being device name or Hostname) of position EPC, geographic coordinate or reader.For example, the intermediate equipment server can send the XML order that its title of indication reader is set to logical name (for example " dock gate 100 ").In some such implementations, logical name will comprise extra civilian address information (for example " warehouse A ") and/or mapping information, for example (x, y, z) coordinate, lat/lon or the like.
The position data that receives in the supply process preferably is stored in this locality, for example is stored in the storer of each RFID reader that is supplied to.When middle equipment when being initiated to the session of reader, it utilizes the Hostname of hard coded to inquire about dns server.Dns server responds with the IP address that is tied to this Hostname, and intermediate equipment can be connected to the RFID reader.
After the RFID reader is supplied to and disposes by the method according to this invention, the RFID reader is read RFID label (step 1035), and will be sent to intermediate equipment server, for example the intermediate equipment server 952 and 954 of Fig. 9 A from the RFID data (being called as " the original result of reading " etc. here sometimes) of RFID label.In preferred implementations more of the present invention, the RFID reader also will be encoded the position data that obtains during the supply process (for example logical name) with the original result of reading and be transmitted (step 1040).This example that reads the result is described with reference to Figure 13 hereinafter.
In some such implementations, these position datas are transmitted with each original result of reading.Mention as this paper other places, logical name has does not need for example implication of device id number of cross reference.Therefore, logical name for surveillance, investigation fault or the IT personnel that otherwise attempt determining reading result's meaning be significant.This anyly for example can carry out via management station 957.
Some implementations of the present invention use other to determine the method for device location.For example, the certain methods that is suitable for wireless device uses the position of summarizing in one or more IEEE 802.11 standards (for example 802.11b) to determine technology, by reference these standards is incorporated into here, is used for all purposes.
Flow chart description such implementations more of the present invention with reference to network chart and Figure 12 of Figure 11.Figure 11 illustrates wireless device 1105, and it is a wireless RF ID reader in this example.In other implementations, wireless device 1105 can be the wireless device of another kind of type, for example has the portable digital-assistant or the laptop computer of wave point.Signal from wireless device 1105 can be by 1101,1102 and 1103 detections of WAP (" WAP "), and these access points are communicated by letter with 1112 with switch 1111.
According to the method 1200 of Figure 12, wireless device 1105 initialization also form related (step 1205) with access point 1101.All 802.11 equipment are all only related with single access point at any time.Therefore, wireless device 1105 can only be related with single access point.Access point 1102 and access point 1103 can " be seen " wireless device 1105, because wireless network is to share medium.But wireless device 1105 is towards having related access point 1101 with it with its direct traffic.
According to the 802.11b standard, wireless device will periodically send specific radio frames (grouping), and they specifically are interpreted as to go to all access points.Specific frame generally depends on implementation, and it generally includes the identifier of particular wireless device.This specific frame will be called as " position frame " etc. here.Therefore, in step 1210, wireless device 1105 sends and is access in a little 1101, the 1102 and 1103 position frames that receive.The position frame comprises identifier, this identifier can be wireless device 1105 MAC Address, certain other identification number, be encoded to the EPC value of RFID equipment, or the like.
When access point received the position frame, access point was forwarded to the management of information server of gathering from various access points with the position frame.Each access point can insert the power level (received signal intensity index or " RSSI ") about the frame of the timestamp that when receives frame and/or reception before frame is forwarded to management server.These data will be called as " IEEE 802.11b position data " etc. here sometimes.
This IEEE 802.11b position data can comprise the data that can be called as " trigdatum ", because these data can be used for by the triangulation technique location of wireless devices.But the IEEE 802.11b position data of some types is not trigdatum strictly speaking.But, other positional informations of these data refers, for example diagram data systematically.
Therefore, in step 1215, access point 1101,1102 and 1103 is inserted into IEEE 802.11b position data in the position frame that is received from wireless device 1105, and the position frame is forwarded to management server 1120.Therefore, management server 1120 will receive a plurality of frames from the device identifier that comprises wireless device 1105 of diverse access point.Switch 1113 is illustrated as being hardwired to management server 1120, Dynamic Host Configuration Protocol server 1125, ldap server 1130 and switch 1111 in Figure 11.Switch 1113 is illustrated as communicating by letter with switch 1112 via network 1160, and network 1160 is LAN (Local Area Network) in this example.But one skilled in the art will appreciate that this is the simple examples how these and other equipment of network 1100 can communicate.For example, switch 1113 can be via communicating by letter with management server 1120, Dynamic Host Configuration Protocol server 1125, ldap server 1130, switch 1112 and switch 1111 such as the such network of Intranet and/or the Internet.
In step 1225, management server 1120 attempts utilizing the IEEE 802.11b position data in the frame of position to determine the position of wireless device 1105.Access point preferably is mapped in the management server, so their position is known.Based on the IEEE 802.11b position data in the particular frame (for example RSSI or timestamp), the management server available algorithm is determined the position of wireless device 1105.
When access point was added to management station, management server 1120 can illustrate the position of wireless device 1105 on a width of cloth map, and this map is pre-configured to be in the management station.Can indicate this position by geographic coordinate.Perhaps (or additionally), some part that management server can be configured to specify map is corresponding to the preposition title, for example " dock gate 101 " or " back storehouse ".
If management server 1120 be can not determine the position of wireless device 1105, then method 1200 finishes.However, the position still can be determined by other methods described herein.But if management server can be determined the position of wireless device 1105, then management server 1120 will be stored this position, and the storer (optional step 1230) of renewable another equipment (for example ldap server 1130).
In step 1235, the DHCPDISCOVER request that wireless device 1105 will have device identifier sends to Dynamic Host Configuration Protocol server 1125.Different with the ad-hoc location frame, the related with it access point of wireless device 1105 (access point 1101) is only gone in the DHCPDISCOVER request.The switch 1111 that access point 1101 is connected to is the point of addition data alternatively, as described elsewhere herein.For example, switch 1111 can be included in position data in the option 82.Switch 1111 is forwarded to Dynamic Host Configuration Protocol server 1125 via switch 1113 with the DHCPDISCOVER request.In some implementations, if Dynamic Host Configuration Protocol server on independent IP subnet, then switch 1113 serves as relay agent, and gateway address is inserted in the DHCPDISCOVER request.
In step 1250, Dynamic Host Configuration Protocol server 1125 searching and managing servers 1120 and/or ldap server 1130, with determine whether with DHCPDISCOVER request in the corresponding position of information (for example id information).If no, then method 1200 finishes.
In such example, Dynamic Host Configuration Protocol server 1125 is receiving DHCPDISCOVER request back searching and managing server 1120 to obtain the position of equipment.Dynamic Host Configuration Protocol server 1125 can use MAC Address, EPC value or the one other identification symbol that is encoded in the DHCPDISCOVER request, so that wireless device 1105 is introduced to management server 1120.Management server 1120 can return to Dynamic Host Configuration Protocol server with the position of RFID equipment via network.Depend on implementation, management server 1120 can return geographic coordinate, or the preposition title, for example " dock gate 101 ".
Dynamic Host Configuration Protocol server 1125 can be inquired about ldap server 1130 to obtain this information by similar mode.If management server 1120 is upgrading ldap server 1130, then Dynamic Host Configuration Protocol server 1125 can obtain these and other data from ldap server 1130.
If device location is determined, then Dynamic Host Configuration Protocol server 1125 determines whether to be suitable for this position and the configuration data that is suitable for the device type of indication in the DHCPDISCOVER request, personality data or the like, as described elsewhere herein.If no, then method 1200 finishes.If this data are found, then Dynamic Host Configuration Protocol server 1125 obtains these data (step 1255) and they is offered wireless device 1105 (step 1260).In this example, determine the position data of equipment in step 1250, for example logical name also is available.Therefore, in step 1255, also obtain these data, and in step 1260, provide it to wireless device 1105.In step 1265, correspondingly supply with wireless device 1105.
After the RFID reader was supplied to and disposes, the RFID reader was ready for routine operation.The RFID reader will be read RFID label (step 1270), and will be sent to the intermediate equipment server from the original result of reading of RFID label, for example the intermediate equipment server 952 of Fig. 9 A and 954 or the intermediate equipment server 1170 of Figure 11.In this example, the RFID reader also will be encoded the position data that obtains during the supply process (for example logical name) with the original result of reading and be transmitted (step 1275).Logical name is significant for the IT personnel of surveillance, investigation fault or the like.
Figure 13 illustrates a kind of example format that the RFID that comprises logical device title and/or device location data reads the result.In this example, the RFID reader is via Ethernet and intermediate equipment server communication, and the RFID label read result 1300 and be coded in the XML document.Therefore, the outermost layer of encapsulation is an ethernet layer 1305.In ethernet layer 1305 IP datagram 1310 and TCP layer 1315.Therefore, XML document 1325 is embedded in the HTTP message 1320, and this HTTP message is encapsulated in the interior TCP/IP grouping of ethernet frame.
In this example, XML document 1325 not only comprises logical name (" dockDoor100 ") but also comprises lat/lon/elevation data, and is as follows:
<？xml?version＝″1.0″encoding＝″UTF-8″>
..
<rfidReader>
<readerName?name＝″dockDoor100″>
<readerLocation>
<locationCoordinates>
<lattitude>053C1F751</lattitude>
<longitude>F50BA5B97</longitude>
<altitude>00006700</altitude>
</locationCoordinates>
</readerLocation>
<readPoint?id＝″1″>
<epc>000000000000000000000001</epc>
</readPoint>
</readerName>
</rfidReader>
In XML document, have single EPC label read value ("＜epc〉000000000000000000000001＜/epc ").
Figure 14 summarizes the process flow diagram be used to use the short-cut method 1400 that the position data that provided by aspects more of the present invention and RFID label read the result.Some steps of method 1400 for example can be carried out by (and/or via) management station, for example the management station 1150 of the management station 957 of Fig. 9 A or Figure 11.
In step 1405, position data and RFID label read the result and are received.In some systems of prior art, the original result of reading can be by utilizing identification number, and for example the MAC Address of reader identifies originating end RFID reader.The original result of reading from a plurality of RFID readers for example is displayed on the display monitor of management station.
Replace be designated the to use by oneself RFID reader of number mark with the original result of reading, according to certain aspects of the invention, read the result via being associated with position and/or function such as logical names such as " dock gate A ", " 22, the 3 layers in buildings, meeting room B ".Therefore, the IT personnel are easier when problem is instructed to determines (step 1415), and/or more promptly handle this problem (step 1420) and solve its (step 1425) when this problem is instructed to.
In one example, the IT personal management is used for the RFID network in factory and the warehouse that is associated.The IT personnel are used for this purpose with management station, and this management station has the screen of demonstration about the information of the various assemblies of network.For example, screen can show the multirow clauses and subclauses usually, the original at least a portion that reads result and relevant position data of these clauses and subclauses indications.In this example, management station comprises that permission IT personnel show that according to various standards RFID reads result's software, and wherein at least some are corresponding to position data.For example, the IT personnel can be presented in certain time frame from ad-hoc location (for example from specific dock gate or specific buildings) all read the result.Therefore, the IT personnel can more easily detect problem (step 1415).
Management station also can be included in the software that automatic notice is provided when (or fault generation) takes place scheduled event.For example, on display screen, can eject the frame of this problem of indication, for example " I did not receive about the message of [logical name of equipment] in 2 hours " or " [logical name of equipment] just sent the message of marker antenna fault " (step 1415).
The IT personnel can more easily handle this problem (step 1420), because indicated problem will be associated with certain location title/logical name.For example, can by interrogating rfid equipment and/or the intermediate equipment that is associated server, by reboot RFID equipment, by notice indicated position or near the people of work change RFID equipment that breaks down or the like, handle problems.After problem is solved (step 1425), management station will continue to receive and monitoring RF ID reads the result.
